Long-term outcomes of metabolic and bariatric surgery: a 10-year study of effectiveness and predictors.
Article in International journal of obesity (2005), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesThis study aimed to evaluate long-term effectiveness of metabolic and bariatric surgery (MBS) over a 10-year period, to identify predictors of therapeutic success and weight loss, and to compare differences between Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). SUBJECTS/
methodsA retrospective cohort study was conducted on patients who underwent MBS between 2010 and 2013 at a Portuguese tertiary hospital (n = 909). Patients who underwent laparoscopic adjustable gastric banding or revisional surgery during follow-up were excluded (n = 280). The 10-year loss to follow-up rate among included participants was 37.2% (n = 147). Clinical data were collected over a 10-year period. Therapeutic success was defined as a percentage excess weight loss (%EWL) of at least 50%. Multivariate logistic or linear regression analyses were performed to identify independent predictors of long-term outcomes.
resultsOf 395 participants included, 89.6% were females, with a mean age of 41.9 ± 10.8 years and a median body mass index (BMI) of 43.8 [40.9; 47.8]Kg/m
conclusionMBS remains an effective long-term treatment for obesity, with RYGB offering superior outcomes compared to SG in our cohort. Our findings highlight the importance of early postoperative weight loss, and baseline BMI as key predictors of long-term outcomes and success after bariatric surgery.
